BY ma? ATTORNEY$ UNITED STATES PATENT OFFICE.

DAVID RANKIN, OF ROSAMOND, ASSIGNOR TO HIMSELF, AND ALBERT WV. BERRY, OFPASADENA, CALIFORNIA.

DOO R-CH ECK.

SPECIFICATION forming part of Letters Patent No. 453,915, dated June 9,1891.

Application filed October 20, 1890- $erial No. 368,662. (No model.)

To all whom it may concern-.-

Be it known that I, DAVID RANKIN, of Rosamond, in the county of Kern andState of California, have invented a new and Improved Door Holder andBuffer, of which the following is a specification, reference being hadto the annexed drawings, forming a part thereof, in which Figure 1. is aperspective view showing the application of my improvement with the doorclosed. Fig. 2 is a vertical longitudinal section with the door open,and Fig. 3 is a horizontal -section taken on line 00 w in Fig. 2.

Similar letters of reference indicate corresponding parts in all theviews.

The object of myinvention is to provide a simple and effective devicefor arresting the motion of a door when thrown open, and for holding thedoor open.

My invention consists in a pivoted arm, provided with a beveled catchand furnished with a chamber in its free end for receiving an elasticbuffer, and a socket adapted to be fitted to the door for receiving theend of the pivoted arm, and a plate for closing the socket when it isdesired to use the device merely as a buffer.

The plate A, which is designed for attachment to the base-board or otherportion of the wall, is apertured to receive the fast-ening-screws, andis furnished With ears a, between which is pivoted the angled arm B uponthe rivet b. The end 0 of the said angled arm B strikes the plate A whenthe arm is in a horizontal position, and serves as a stop for holdingthe arm in position to engage the socket 0 attached to the door.

In the free end of the arm B is formed a cavity 01 for receiving theelastic bufier e, which projects beyond the end of the arm. The free endof the arm B on its under surface is provided with a beveled lug f forengaging the lip g of the socket O. The socket O is provided with aflange or face-plate h, which is apertured to receive the screws bywhich it is attached to the door, and to the said face-plate, at oneside of the aperture in which the arm 13 is received, is pivoted a plate2', which may be turned so as to prevent the arm B from entering thecavity of the socket. The pivoted plate i is furnished with a handle j,for convenience in turning the said plate. The socket O is inserted in amortise formed. in the door and secured in place by screws, and theplate A is fastened to the base-board in such a position as to bring theend of the arm 13 opposite the opening of the socket C as the door isopened, so that as the lip g of the socket strikes the beveled lug f thearm B is lifted and the said beveled lug drops behind the lip g, therebyholding the door in an 7 open position. Should the door be openedviolently, the elastic buffer 6 arrests its motion by striking .thebottom of the socket G.

hen it is desired to use the device merely as a buffer, the pivotedplate t is turned so as to close the opening of the socket, when thebuffer will strike the plate 1 instead of the socket.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a door holder and butter, the combination, witha pivoted arm, of a socket into which the arm is adapted to enter and tobe engaged thereby, provided with a pivoted plate for closing saidsocket, substantially as and for the purpose set forth.

2. In a door holder and buffer, the combination of the plate A, providedwith the ears a, the angled arm 13, pivoted between the ears a andprovided with the beveled lug f and cavity d, the elastic buffer 6,inserted in the said cavity, the socket 0, provided with the lip g, andthe pivot-ed plate 1', adapted to close the opening of the socket,substantially as specified.

DAVID RANKIN.
